Which cloud service model provides software as a service that you access over the internet with no installation?

• A. IaaS
• B. PaaS
• C. SaaS
• D. DaaS

Answer: (C)

Software you access over the internet with no local installation is provided as a service in this model. You typically use it through a web browser or a lightweight client, and the provider hosts the application, handles updates, security, and maintenance. Because the software is delivered as a service, there’s no need to install or manage it on your device. This contrasts with other models where you manage more of the underlying layers. Infrastructures-as-a-service offers raw computing resources like virtual machines and storage that you configure and maintain. Platform-as-a-service provides a managed environment to develop and run your own applications, while you still manage your code and data. Desktop or data services deliver virtual desktops or data resources rather than a ready-to-use software application.
